IMPROVEMENT IN SPRING-SEATS.

Specification forming partrof Letters Patent No. 56,200, dated July 10, 1866.

To all whom it may concern:

Be it known that I, LUTHER W. FILLE- BROWN, Jr., of Wayne, in the county of Kenmaterial, and provided with legs a a a a, if

necessary. To this frame the edges of the covering B of the cushion should be fastened b v tacks or other suitable equivalents. Beneath the said coveringV there may be a stuifing, a', of hair or other elastic material, which ma y rest on a layer, b', of cloth.

Un a frame, G, composed of two elastic slats, c c, and two bars, b b, of wood, arranged as represented, I dispose a series of elastic arches or bows of steel, D D D, each of such bows being fastened at or near its ends to the two slats o c, and being formed as exhibited in Figs. l and 2.

The combination of the frame C and the series of elastic bows is to be placed within the frame A, with the bows upward and against the under side of the layer b of cloth, and is to be iirmly forced upward against such layer, after which the two end bars, b b, of the frame should be secured to the end bars of the frame A by screws s s.- In this way a cushion or elastic seat can be constructed to be of great utility, one capable of being easily rounded or set up in case of any sagging of its springs, as, after such may have taken place, it will only be necessary to remove the screws s s and press the frame C still higher up into the frame A, so as to again tighten the covering and cushion on the springs. After the accomplishment of this the two frames may be fastened together as before, the screws going into fresh or other holes made in the frame A.

The arch-springs, formed as represented, operate to crown the scat as well as to impart to it elasticity. In this respect each performs a function not common to an ordinary spiral spring.

I claim- The improved elastic seat, made as described-viz., of the adjustable frame C, the series ot' bow or arch springs D D D, the frame A, and the ieXile covering E, arranged and combined together substantially as set forth.
